ThermaPlus Glass for Greater Energy Savings

Energy requirements are becoming more stringent, with lower U-factors and solar heat gain coefficients necessary to be eligible for federal energy tax credits. That's why we at Kolbe have added the option of ThermaPlus glass for most of our products.

Surface 2 is coated with LoE²-270 to reject the sun's heat OR with LoE³-366 for an ideal balance of solar control and high visibility

The "airspace" is filled with argon gas to further prevent solar heat gain in summer and heat loss in winter; no argon is available upon request; argon gas is not used in units to be shipped to or through high altitude areas

Surface 4 has a ThermaPlus coating for greater thermal performance and durability
